1. A method of producing a blank having a plurality of component positions for electronic components, the method which comprises the following method steps:
producing at least one of a carrier plate and a first plastic layer from a plastic compound being more highly crosslinked in a lower region than in an upper region;
fitting a semiconductor chip in each of the component positions of the blank, and thereby forming a bead of plastic compound of the first plastic layer, the bead surrounding marginal sides of the semiconductor chip;
applying a second plastic layer; and
curing the plastic layers for forming a self-supporting, dimensionally stable plastic plate with embedded semiconductor chips in the component positions.
